  • Publication number: 20160277753
    Abstract: An image processing apparatus and a method thereof are provided. The image processing apparatus includes at least one processor configured to implement: a decoder which decodes input image data; and a rendering module which renders the decoded image data according to a rendering cycle which corresponds to a refresh rate of a display to display a plurality of image frames of the image data, wherein the decoder decodes the input image data only when the processor is not being in use for rendering by the rendering module.

  • Publication number: 20150124540
    Abstract: A system including a circuit integrated with a semiconductor is provided. The system includes a first data line, a second data line, and a first sense amp configured to sense and amplify data of the first data line. The first sense amp is also configured to transfer the amplified data to the second data line in response to a third control signal. The system also includes a control signal generation circuit configured to generate a first control signal for controlling a precharge of the first data line and a second control signal for controlling a reset of the second data line in response to a preparatory signal and a third control signal. The third control signal is generated in response to the first control signal and the second control signal.
